Arduino Uno WiFi Rev2 upgrades the classic UNO with built-in Wi-Fi & Bluetooth® Low Energy via the u-blox NINA-W102 module, a secure ATECC608 crypto chip for TLS, and a 6-axis IMU (accelerometer + gyro)—all while keeping the familiar UNO form factor for shields and classroom workflows. It’s the easiest entry to IoT dashboards, data logging, and wireless robotics in the Philippines.
UNO, Now Wireless — Wi-Fi + BLE, IMU & Crypto On-Board
- Modern connectivity: Wi-Fi 2.4 GHz and BLE built in; use Arduino’s WiFiNINA and ArduinoBLE libraries for fast prototypes.
- Secure by design: ATECC608 hardware crypto for secure connections and certificates.
- Motion sensing: 6-axis IMU for orientation, taps, tilt—great for wearables, robots, UI gestures.
- Still an UNO: 14 digital I/O (5 PWM), 6 analog, 5 V logic, R3-compatible footprint.
- ATmega4809 headroom: 48 KB Flash / 6 KB SRAM for larger sketches than classic UNO.
What you can build
- IoT dashboards: stream sensor data to web/MQTT with BME280, DHT22, ToF
- Motion-aware projects: gesture-controlled lamps, counters, tilt alarms using the on-board IMU
- Wireless robots: BLE teleop + Wi-Fi telemetry; add a motor shield and OLED/TFT
- Secure devices: TLS to APIs with the crypto chip; log to microSD+RTC shields
Starter bundles (quick picks)
- Wi-Fi Starter: Uno WiFi Rev2 + USB data cable + sensor pack + 0.96″–1.3″ OLED
- Motion Kit: Uno WiFi Rev2 + IMU examples + buzzer + LEDs + proto shield
- Robot Builder: Uno WiFi Rev2 + TB6612FNG + 2WD chassis + battery/PSU
Recommended add-ons
- USB data cable (check photos for connector) & 5 V/7–12 V power
- Shields (motor, relay, Ethernet, proto)
- Displays (OLED/LCD/TFT) & sensors
- Tools & multimeter for bring-up
- Cases & mounting (tall lids for stacked shields)

Pinout & power notes
- PWM count: Uno WiFi Rev2 exposes 5 PWM pins (different from UNO R3’s 6).
- Libraries: Use WiFiNINA for Wi-Fi and ArduinoBLE for BLE; IMU with Arduino_LSM6DS3.
- Porting sketches: A compatibility layer lets many ATmega328P UNO sketches run on ATmega4809; direct register code may need changes.

FAQs – Arduino Uno WiFi Rev2 (Philippines)
Is this compatible with my existing UNO shields?
Yes—same UNO R3 footprint and 5 V logic. For SPI shields, use the ICSP header and confirm chip-select pins.
How do I get online quickly?
Install the WiFiNINA library in the Arduino IDE and try the WiFi examples (ScanNetworks, ConnectWithWPA, SimpleWebServer, etc.).
Does it support Bluetooth®?
Yes—the NINA-W102 module provides BLE (and classic Bluetooth®). Use the ArduinoBLE examples to start.
Do you ship nationwide and support school/corporate orders?
Yes. We ship nationwide across the Philippines and can prepare classroom bundles and bulk quotations on request.
Manila stock. Order before 16:00 PHT, ships today via J&T or LBC. Provincial: 1–3 working days.
Schools / class POs: we accept Purchase Orders for accredited schools and universities. contact us with your PO details.
Returns: 7-day inspection window for DOA units. Email proof of issue and we ship a replacement.
